Butt welding machine-spot welding machine industry trends

Brass decorative strips are generally small and thin, and are mainly used for decoration and splicing of bamboo fiber boards, marble, and solid wood boards. The quantity to be connected is generally not very large, but the value is great, so it would be a pity to waste it. It is the best choice to use Xinxing semi-automatic butt welding machine for welding.

Most of the metal accessories to be welded by textile machinery are made of low carbon steel or medium carbon steel. After all, they are mechanical products, the output is not very large, and the price of low carbon steel is low. In order to save costs, semi-automatic butt welding machines and butt welding machines are generally chosen for welding.

Metal pipes include iron pipes, stainless steel pipes, copper alloy pipes, aluminum alloy pipes, etc. They are mainly used in furniture, boilers, chemical industry, pipelines, planting sheds, air conditioners, cold storage, aerospace, aviation, electrical appliances, agriculture, and electromechanical.

The material diameter is 6.7mm low carbon steel O-shaped chain ring, and the outer ring diameter is 63mm. It is welded by Xinxing UN6 pneumatic automatic butt welding machine.

Flash butt welding of bar and wire billets is a process in which adjacent billets of bars or wires are welded together on the rolling production line to achieve continuous rolling. It has good welding quality, fast speed and high efficiency, can reduce the amount of scrap and reduce the loss of components. It is welded firmly and the properties of the welded parts are the same as those of the base material. Ability

Wire rods include low carbon steel wire rods, medium and high carbon steel wire rods. It is an economical and efficient steel material with high tensile strength and yield strength, good plasticity, and low relaxation performance. It is mainly used as a blank for wire drawing and is also widely used in the construction of cement products, bridges, nuclear power plants, high-rise long-span buildings, highways, etc.

Wire rope is mainly used for lifting, pulling, tightening and carrying purposes such as electric hoists, winches, cranes, elevators, airplanes, ships, cable cars, ropeways, etc. During twisting, if the wire is broken or two wires need to be pulled through the mold, quick butt jointing is required. Nowadays, resistance butt welding machines and medium frequency butt welding machines are mainly used for welding.

Although almost all steel and non-ferrous metals can be flash butt welded, most of them now only flash butt weld iron pipes, steel pipes, flat iron flanges, large-section steel bars, etc. Due to the high price, resistance butt welding is used for other materials.

Low carbon steel has high resistivity. When melted at high temperature, carbon elements produce protective atmospheres of CO and CO2 and do not produce high melting point oxides. Therefore, the weldability is good. Medium carbon steel has higher carbon content than low carbon steel, has higher resistivity, crystallization interval, high temperature strength and is easy to harden. It is necessary to increase the upsetting force and upsetting allowance
